PROCESS OF PREVENTING THE FORMATION OF CLINKER IN GAS-PRODUCERS.

Specification of Letters Patent.

Patented Jan. 2, 19L 6.

Application filed July 27, 1904. Serial No. 218,357.

To all whom it may concern.-

Be it known that I, J AMES E. SHEAFFER, a citizen of the United States,residing at Burnham, Pennsylvania, have invented certain Improvements inProcesses of Preventing the Formation of Olinker in Gas-Producers, ofwhich the following is a specification.

The object of my invention is to prevent clinker forming on the walls ofa gas-producer, which would interfere with the ordinary and continuousoperation of the producer. This object I attain by projecting jets orstreams of water against the walls of the producer, with the result thatmaterial which would otherwise produce clinker and attach itself to thewalls is softened and prevented from adhering to the walls, so that itwill be fed do wnward into the ash-hopper with the ashes.

In the accompanying drawings, Figure 1 is a view showing the applicationof my invention to a producer in which the material is agitated byrevolving blades. Fig. 2 is a view showing the application of myinvention to a producer of the type in which the material is notagitated by revolving blades, and Fig. 3 is an enlarged sectional viewof one of the arms.

My invention can be used in connection with any gas-producer, the objectbeing to prevent the accumulation of clinker on the walls of theproducer.

In carrying out my invention I may use it either in connection with aproducer with revolving blades which break up and move the clinker outof the heat zone or in connection with a gravity-fed producer in whichthe agitating-blades are absent.

In the producer shown in Fig. 1 small quantities of water are projectedfrom the rotating arms against the walls of the producer, which willbreak up the clinker and prevent it adhering to the walls, while in Fig.2 a waterpipe is situated above the hot Zone of the producer and wateris allowed to escape from this pipe and trickle down the walls oftheproducer, breaking up the clinker at the walls, and thus preventing theclinker adhering to them.

I will now proceed to describe in detail the producer shown in Fig 1. Arepresents the cylindrical body of the producer, a the taperingash-hopper at the bottom of the same, and a the water-sealed ash-pit. Bis a central air-pipe having an air-distributing head 6. A is thegas-outlet of the producer, and C is one of the valved feeders for thefuel. The producer has a central hollow vertical shaft D, provided withprojecting hollow arms D, which are situated in the hot zone of the fuelthat is to say, between the bed of ashes in the ash-hopper and the greenfuel in the upper portion of the producer. These arms extend very nearthe walls of the producer and are for the purpose of agitating andstirring the mass of fuel in the producer, so as to insure the properflow of air therethrough and to break up the clinker that may be formedtherein. Each of the arms D is water-cooled, the water being conveyedthereto through a central pipe din the hollow shaft D, and branches d ofthis pipe extend into the hollow arms D, the water being delivered bythese branches to the outer end of each hollow arm and returning throughthe arms and hollow shaft to a discharge-pipe d above the top of thefurnace. I find in this type of producer the clinker will form on thewalls to such an extent in many instances as to interfere with therotation of the arms, and, in fact, in some instances stopping therotation of the arms altogether. Then the clinker has to be cut awayaccumulation of clinker on the walls of the producer, and, in fact, willtend to break up the clinker, which will be carried down by the rotatingarms. This particular form of producer is set forth and claimed inacompanion application filed of even date herewith, Serial No. 218,352,as a joint invention by Orville O. Skinner and James E. Sheaffer.

Referring now to Fig. 2, F is the body of another form of producer,shaped as shown in the drawings, having a gas-outletf, a grate G, andafuel-feeding hopper O. In this instance a recess f is formed in thewalls of the producer, and a pipe I rests in this recess and has outletsz' for the escape of water which is fed into the pipe. This watertrickles down the jected into the mass of fuel adjacent to the Walls ofthe producer Where clinker usually forms.

clinker usually forms, substantially as described.

3. The mode herein described of preventing the formation of clinker in agas-producer, said mode consisting in projecting jets or streams ofWater into the incandescent mass of fuel in the producer at pointsadjacent to the Walls thereof, and agitating the mass of fuel,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

JAMES E. SHEAFFER.
